Hi,

After the latest update, the image from my webcam is displaying as just black (I've tried in Cheese, Skype, and guvcview and got the same result). I've double-checked that I didn't accidentally turn off my webcam, but I haven't.

I've been looking around some other threads, and I've included the outputs of some of the common requests for information here:

The output of lsusb is:
Code:

The output of ls /dev/v* is:
Code:
/dev/vcs   /dev/vcs2  /dev/vcs4  /dev/vcs6   /dev/vcsa   /dev/vcsa2  /dev/vcsa4  /dev/vcsa6   /dev/vga_arbiter

Running Cheese through the terminal gets this:

I've tried this:
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so cheese

and also

LD_PRELOAD=/usr/lib/libv4l2/v4l2compat.so cheese

neither of which had any affect.

Any ideas on what to try next?

Thanks,
sky.
